Re: Importing from Outlook PST to Gmail - Unknown Sender
Computer email program (please specify: Apple Mail, Outlook, Thunderbird, etc)
has anyone found a workaround for this yet?
i'm having the same problem....emails created in outlook when i was formerly on an exchange server and were sent/received with other former users of that exchange server all show up as (unknown sender) in gmail.
this thread started 8 months ago and there are others going back almost a year
still no solution...?
